A dozen employees at three U.S. airports were identified as having potential ties to terrorists, according to Freedom of Information Act requests filed by FOX 25’s Washington Bureau.

But those 12 workers are just a fraction of 73 private employees at nearly 40 airports across the nation flagged for ties to terror in a June 2015 report from the Homeland Security Inspector General’s Office.

FOIA requests identified two employees at Logan International Airport in Boston, Mass., four employees at Hartsfield-Jackson Atlanta International Airport in Georgiaand six employees at Seattle-Tacoma International Airport in Washington.

The 2015 report did not reveal where the 73 workers were employed.

Consider what it takes to even get to terror ties. Members of groups with a history of terror ties like CAIR are not on the list. If they were, those numbers would be far higher.
